Yuji's Domain Expansion: What it Means for Jujutsu Kaisen

Why does Yuji's Domain Expansion matter in Jujutsu Kaisen?

Revealed in Chapter #264, Yuji's Domain Expansion resembles a train station. His dominion is cast by the hand sign linked to Kṣitigarbha, a Buddhist bodhisattva guiding wayward souls toward enlightenment. This link is important because it reflects Yuji's interest with the idea of a proper dying and his will to assist others. Additionally suggesting Yuji perhaps guiding Sukuna to enlightenment in their last combat is his hand sign and his domain's train station-like appearance.

In Yuji's Domain Expansion, what does Kṣitigarbha's name, "Earth Store" or "Earth Womb," suggest?

The Sanskrit translation of Kṣitigarbha, "Earth Store," or "Earth Womb," would fit Yuji's creation as the ultimate vessel by Kenjaku, nearly as a perfect form of the cursed Wombs. This link emphasizes Yuji's special position as a vessel and the possible influence of his origin on his capacity.

In what way does Kṣitigarbha's protection of children relate to Yuji and Sukuna?

Particularly for those who were stillborn, aborted, or miscarried, Kṣitigarbha is regarded as guardian of children's souls. This may be especially important in Jujutsu Kaisen since Sukuna's past is becoming clear. Sukuna ties his fate to Yuji by implying he ate his twin in the womb out of hunger, and by calling himself an unhappy child. This link would suggest that Yuji's Domain Expansion is supposed to guard and direction Sukuna's soul.

In what way does Yuji's Domain Expansion relate to Sukuna's hand sign for his own Domain Expansion?

Declared the bodhisattva of heaven, Kṣitigarbha descended to hell to rescue doomed souls. Fascinatingly, Sukuna casts his domain using the hand sign connected with Enamten, the king of hell. < This points to a complicated relationship between Yuji and Sukuna whereby Yuji might be able to steer Sukuna toward actual enlightenment and atonement.

Why is the Kitakami Station significant for Yuji's Domain Expansion?

The platform shown in the most recent chapter comes from the Kitakami Station in Iwate, the author's hometown. The architecture of the platform and the fact that Yuji is on the Tohoku Shinkansen track traveling north towards Shin-Aomori point to Yuji perhaps leading Sukuna into actual enlightenment. Starting again and enlightenment in Buddhism, which could be a fresh start for Sukuna, "going north" is connected with in Buddhism.

Might the Yuji Domain Expansion rail station serve as the hereafter?

Many supporters have read the train station image as the afterlife or a sort of limbo. The last page of Chapter #264, which reflects the start of Chapter #236, and Sukuna's resemblance to Yuji in the scene help to justify this argument. Yuji or Sukuna, however, are unlikely to have passed away since Sukuna is shown utilizing Reverse Cursed Technique, which runs against this theory. Still, Yuji's Domain Expansion has a lot of uncharted territory.
